4 Claims. (01. 173-356) This invention relates to means for convenadapted to receive, for example, cowl, tail or iently carrying replacement bulbs for use on signal light bulbs. automobiles and consists in the provision of a Each of the sockets in the present instance is device provided with a plurality of lamp sockets provided with one or more bayonet slots 22 for for accommodating the bulbs, together with accommodating the pin or pins 23 with which 60 means for efficiently locking the bulbs in the the pins of the lamp bulbs 24 are usually prosockets against unauthorized removal. vided for retaining the bulbs within the sockets.

The invention, together with its numerous obn e fee-r e Of the panel there is p jects and advantages, will be best understood vided a locking plate 25 that is slidehly secured 10 from a study of the following description, taken to the panel through the d u of belt a d 65 in connection with the accompanying drawings, slot means 26 as shown in Figure 5.

On the drum 13 is windable the the inhel side of the Panel 0 a block 31 of cord 14 of a trouble light 15, the cord 14 operating sula n material and a p u ty f sp c nin a longitudinal slot 16 provided therefor in the test fingers 32 are s y ecured to the block. front of the housing 12 as shown As shown in Figure 3, the contact fingers are 49 In this connection, it will also be n t d that, electrically connected with the contacts of the provided on one end of the drum 13, is a conlamp socketsthrough the medium of wires 33. ductor ring 17 insulated from the drum as t In this connection it also will be noted that one 18.

One end of the 0nd one of the contact fingers 32 has electrically electric cord 14 is connected with the ring 17 connected thereto one end of a lead wire 35 for in any suitable manner for supplying current to supplying current to the bulbs from the wiring the lamp 15 from any suitable source of supply, system of the automobile. preferably from the lighting system of the autosuitably journaled at the rear side of the panel 50 mobile. 10 is a roller 36 provided at one end with a Suitably mounted on the panel 10 are a pluhandle 37 to facilitate turning of the roller. The rality of lamp sockets 21 certain of which, as roller 36 comprises a cylindrical body of insulatclearly shown in Figure 6, are provided with ing material to which is suitably secured a subclouble contacts for accommodating automobile stantially sleeve-like member 38 of conductive headlight bulbs, while other of the sockets are material, the member 38 having portions slitted and removed for exposing, in the path of the contact fingers 32, portions of the insulation body 36 of the roller as the roller is revolved for making contacts between the sleeve 38 and the desired one of the spring fingers 32 to test a selected bulb 24.

While of course the device may be mounted on any suitable support within the automobile it has been preferable to mount the same on the dashboard 39 of the automobile beneath the hood 40 as shown in Figure 1, and when so mounted it will be noted that the only parts of the device which are accessible are the bulbs and the keyhole of the lock 27, the dash board 39 closing the open and rear side of the device as is apparent.

The use of the device is thought to be clear from the foregoing description, it being obvious that whenever desired the trouble light can be readily pulled to unwind its cord 14 to bring the light 15 into proximity to the part being repaired; while when it is desired to remove one of the bulbs 24, the particular bulb may first be tested by properly manipulating the handle 3'7 to rotate the roller 36 for closing the circuit to the selected bulb. To remove the bulb from its socket, the lock 27 is operated for shifting the plate 25 to withdraw a pin 30 associated with the plate from the bayonet slot of the socket thus permitting the bulb 24 to be rotated relative to its socket and subsequently withdrawn therefrom.

It will be seen from the foregoing that a simple yet thoroughly practical and efficient device is provided for carrying replacement bulbs for use on automobiles and for so looking the bulbs as to prevent unauthorized removal thereof.

What is claimed is:

1. A holder for automobile light bulbs comprising a panel provided with a plurality of lamp sockets having slots in the walls thereof for re ceiving the stems of bulbs of the type provided with lateral retaining pins, a locking plate slidably mounted on the panel and provided with projections arranged to engage in the bayonet slots behind the pins of the lamp bulb stems for locking the bulbs against rotation in the sockets, and a key controlled lock device mounted on the panel engaged with said plate for shifting it and for securing it in position.

2. A device of the class described comprising a panel provided with a lamp bulb socket, having the common bayonet slots for receiving the common lateral pins of the bulb stem for retaining the bulb in the socket when the bulb stem is inserted in the socket and turned to move the pins into engagement with the bayonet slots, and a key controlled locking device mounted on the panel and including a member shiftable relative to the panel and having a projection adapted to enter a bayonet slot to engage therein behind the pin of the bulb stem after the bulb stem has been turned to move the pin into final retaining position within the bayonet slot of the socket to thereby secure the bulb within the socket against unauthorized removal.

3. In a device of the character described, a support, a plurality of lamp sockets mounted on the support and each provided with the com mon bayonet slot for receiving the common lateral pin of bulb stem, a key controlled lock mounted on the support and including a bolt, a locking plate slidably mounted on the support connected with the bolt to shift therewith, and provided with openings through which the sockets extend and a projection on the plate at the edge of each opening to enter a bayonet slot to secure the pin of a bulb stem within said slot.

i. In a device of the character described, a panel, a plurality of lamp sockets mounted on the panel and provided with the common bayonet slots for receiving the common lateral pins on the stems of lamp bulbs for retaining the bulbs in the sockets against casual displacement, a plate shiftably mounted on the panel and provided with apertures for accommodating certain of the lamp sockets, projections on the plate at the edge of the openings for projecting into bayonet slots provided in the sockets accommodated by said openings to prevent removal of the bulbs, additional projections on the edge portion of the plate to project into bayonet slots in other of the sockets, a key controlled lock, and an operating connection between the bolt of the lock and said plate for shifting the latter into and out of locking position.
